In April 2012, Madison Bumgarner signed a 5-year, $35 million extension with the Giants.
The deal also includes two club options for 2018 and 2019 at $12 million each season.
As of now, the Giants don't have any plans to discuss an extension with their Opening Day starter.
"I've addressed it with Madison and his agent directly already and just said 'Let's make sure when the timing's right, let's talk about this. And I don't want to rush you but at the same time I want you to know that our door is open when you see the right time,'" Giants GM Bobby Evans explained on KNBR 680 on Thursday morning. "One of the challenges of course, given that he has four more years on his current deal, one of the values to the next contract will be the years.
"It's hard to put the number of years that he might want on top of the current list of four years."
Upon reporting to spring training on Wednesday, Bumgarner said he's not thinking about his contract and he won't push for an extension anytime soon.
"Not at all -- I'm extremely happy for (the other starters)," Bumgarner said. "If everything goes the way I want and what I work for, then that'll come along in due time. I'm not at all worried about that. When I signed my deal I knew what I wanted to do, but you never know what's going to happen. I was prepared for that."
The Giants selected Bumgarner with the 10th overall pick in the 2007 draft. He made his big-league debut in 2009, and recorded 18 starts in 2010.
In 2011, he went 13-13 with a 3.21 ERA. When he inked his deal, he was just 22 years old.
"There will be a time when it's right and Madison and his agent will want to approach this," Evans added. "I don't know exactly when that will be. From talking to them, I don't suspect that it will be any time this season. Maybe in the offesason, maybe early next year ... I just don't know. I think that they know there's openness on our end to talk about it at the right time."
Over 96 starts from 2013 to 2015, Bumgarner went 49-28 with a 2.90 ERA.
He struggled in his first two 2012 postseason starts, but tossed seven shutout innings in Game 2 of the World Series.
He became a living legend in 2014, when he racked up a 1.03 ERA over 52.2 postseason innings.
He won't turn 27 years old until Aug. 1 and it sounds like he and the Giants are on the same page.
"Four years out is probably too much time left," Evans said in regards to hammering out an extension. "But when you get to three years or less, it certainly could increase the necessity to talk sooner than later.
"It's not expected that you would tear up the current contract as much as you would be putting an extension on it."
